EDWARD S. SNOVER, OF TOLEDO, OHIO.

LOOM-FASTENER.

Application filed September 5, 1916.

To all whom it may concern:

Be it known that I, EDWARD S. SNovER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Loom-Fastener; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to loom fasteners, and it has for its object to provide an efficient, simple loom fastener for securing looms used for insulating wires in position in terminal boxes or in other places where looms or flexible tubes are to be secured in position for the purpose of insulating the electrical wire connections in systems or in devices of diiferent kinds to prevent pulling away of the loom from the part or device from which the Wire carrying the electric current is to be insulated. It particularly has for its object to provide a simple, inexpensive fastener which may be readily applied and may be used in connection with any device into which an electric Wire is to pass.

Constructions containing the invention may partake of different forms and may be used in securing cylindrical bodies in posi-- tion to be used for a great variety of purposes. I have selected one form of construction containing the invention for purposes of illustration to show that the invention when applied and embodied is practical.

Figure 1 of the drawing illustrates a loom fastener containing the invention and shows the same in connection with a terminal box for securing looms therein to prevent withdrawal of the loom. Fig. 2 is a perspective view of the loom fastener showing the posi tion of a loom when the same is about to be secured by the loom fastener.

1 is a terminal box having a suitable cover which may be secured to the box by means of lugs 2. The box may be provided with a plurality of openings or may be provided with a plurality of knockout blanks 3, of a form well known in the art. The wire 4 is inserted through the openings formed by punching the knockout blanks from the box, together with the insulating loom 5 Specification of Letters Patent.

which surrounds the wire 4. The looms, a plurality of which are shown in Fig. 1, are secured by the fasteners 6 located within the terminal box, as shown in the drawing. The loom fastener 6, however, may be placed in any suitable position for properly engaging and anchoring the loom. It is placed in that position which will prevent the movement of the loom which it is desired to restrain. It may be placed both on the inside and the outside of the member through which the wire passes, if desired, in order to prevent movement of the loom in either direction. The position shown in the drawing is the position that the loom fastener is commonly placed, namely, to prevent the end of the loom from being withdrawn from the box.

The loom fastener 6 is formed of wire which makes it exceedingly cheap in its construction. The wire is formed in a circular looped central portion 10 slightly larger than the loom 5, which is to be anchored by the loom fastener. It is also provided with two laterally extending arms 11 formed by bending the ends of the loop into the form of a hook 12. The ends of the hook 12 are curved upward as at 13 and extend over the circular central looped portion of the loom fastener 6 to above the interior of the looped portion 10 and so as to engage with the loom 5 when the loom 5 is passed through the central circular looped portion 10. The ends of the hooks 12 and the upwardly curved portions 13 are sharpened as at 15. The sharpened portions are preferably formed by cutting the wire at an angle to the axis of the wire at its ends, so that a smooth, rounded, curved surface 16 will be presented to the loom 5 as it is pushed up through the central looped circular portion 10, and as it is so inserted the ends of the hooks 12 will be easily spread by the wedge action of the loom between the smooth, inwardly inclined surfaces 16, but upon an attempt to withdraw the loom the ends of the hooks 12 will, by reason of the inclined surfaces 15 which form sharp, beveled ends or points of the hooks 12, engage with the loom, and the more the loom is pulled, will penetrate the loom the more. hen the loom is placed in position to hold the loom in position with reference to a member from which the wire is to be insulated, the arms 11 will preferably rest upon the surface of the member and the loom fas tener being elastic will, when the loom is pulled, cause the arms 11 to bend and force the ends of the hooks 1:2 inward, thus causing the ends of the hooks 12 to further penetrate the loom and securely hold the loom in position. The arms 11, moreover, operate to swing the points outward when the loom fastener is pushed on to the end of the loom by pressure on the arms. The wire being yielding, it bends along the arms and consequently swings the points outward. Thus the points are separated and prevent them from resisting the insertion of the loom into the loom fastener. This is particularly true where the loop is small and there is friction or resistance in pushing the 100111 through the loop.

In Fig. 1 is one loom 5 secured in position in the lower side of the box, and another loom secured in position at the bottom of the box.

I claim:

1. A loom fastener formed of looped wire having points extending over the loop of the wire.

2. A loom fastener formed of wire having a circular looped portion for surrounding the loom, its ends terminating in beveled points located above the looped portion and in position to engage the loom above the looped portion.

3. A loom fastener formed of a looped wire, the ends of the wire located above the looped portion and inclined upward and inward with respect to the looped portion.

A loom fastener formed of a circular looped wire, its ends bent to form laterally extending yielding arms and terminating in engaging points located over the interior of the looped portion. I

A loom fastener formed of a circular looped wire, its ends bent to form laterally extending yielding arms and terminating in upwardly and inwardly inclined ends.

6. A loom fastener formed of a circular looped wire, its ends bent to form laterally extending yielding arms and terminating in upwardly and inwardly inclined ends, the ends having beveled points.

7. A loom fastener formed of a circular looped wire, its ends bent to form laterally extending yielding arms and terminating in upwardly and inwardly inclined. ends, each end cut in a plane at an angle to the axis of the wire to form beveled engaging surfaces.

8. A loom fastener formed of a looped wire terminating in yielding loom engaging points.

9. A loom fastener formed of a looped wire terminating in inclined oppositely disposed ends located above the looped portion.

In testimony whereof, I have hereunto signed my name to this specification.
